Air Exchangers

The United States Environmental Protection Agency warns that “the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities…For many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.”

Is your home trapping unhealthy, stale air?  Using an air exchanger to supply your home with fresh air is one of the most effective ways to reduce indoor air pollutants.   Let your family breathe easier. Improperly ventilated homes are full of indoor air pollutants from cleaning agents, carpeting, paint, construction materials, cosmetics, smoke, formaldehyde, radon and lead.  New homes are even more susceptible to improper ventilation and stale air due to weather-tight construction. 

HRV - Heat Recovery Ventilator

The heat recovery ventilator (HRV) is designed to provide continuous or timed ventilation throughout a home, and recover the heat carried in the exhausted stale air.

The ventilation rate of a traditionally leaky, drafty home is determined by the weather; the outdoor temperature dives stack effect in the home, and the wind just plain blows right through! The colder and windier it gets, the better ventilated your house is. When you build a tight home with a high-quality ventilation system, you control the ventilation rate. Complaints you may have heard about stuffiness and moisture problems in tight houses come from houses where the builder did not install a ventilation system commensurate with the quality of the house, or the system is not being controlled properly. HRVs can be retrofit in most existing homes, but a blower door test (check with your electric utility or heating contractor) should be performed first. HRVs are generally only used in homes which require mechanical ventilation, usually homes with a natural ventilation rate of less than .35 ACH.

The HRV provides several unique benefits as a mechanical ventilation system. First, it is a balanced-type ventilation system, meaning it removes and replaces equal volumes of air from the home. No pressure imbalances occur in the house because of the HRV operating, which improves energy efficiency, comfort and safety. The HRV alone will not cause combustion appliance backdrafting, increased vapor transmission into the structure and insulation of the house, or cold drafts. Second, the HRV recovers 60 to 75% of the heat in the exhaust air, and returns it to the home. Some HRVs (properly called Energy Recovery Ventilators, or ERVs) will recover moisture from the exhaust stream as well, helping to maintain indoor humidity in cold climates. Third, the HRV is usually located in a closet or utility room, making for a quiet ventilation system. You won't even notice a properly installed HRV operating in most of the house. Fourth, the HRV replaces several bath and utility room fans with a single high-quality, long-lived system, which may run continuously or intermittently. Fifth, an HRV allows a tight, well-insulated home which will only have a 2-4 degree F inside temperature difference between the floor and ceiling, for exceptional comfort.

HRVs typically use about 100 to 200 Watts per hour of electrical energy. Compare this usage to the 2000 to 4000 Watts per hour of heating energy typically saved by building a tight home instead of a leaky, drafty home. Controls include timers for scheduled ventilation, demand switches for high-speed ventilation of bathrooms, utility rooms and kitchens (although a range hood is still needed), humidistats to control moisture levels in the home and various gas sensors. HRVs require their own duct system, except for some installations where the forced air system and HRV share some ducts. HRV ducts are usually 6" to 8", and require sealing and insulation (like any good duct system) when outside the thermal envelope.

Remember: When you install an HRV, YOU control the ventilation in your home, not the weather!
